7 Claims. (c1. 20-522) I This invention relates to improvements inwindow construction in which two or more sashes are slidably mounted inthe window frame, my invention relating primarily to the construction ofthe slides supported by the window frame and which engage the saidsashes in their sliding movement.

One object of the invention is to provide a window cons'truction whereinthe sashes may be removably mounted in the window frame, and the slideswhich engage the sashes may be adjusted to various positions toaccommodate variations which may occur in the window frame, per set, andalso to accommodate various widths of sashes even though the frame maybecome warped or distorted.

A further object is the provision of-novel threaded members for movingthe slide bearing inwardly or outwardly from one of the sash stiles tomaintain substantially constant pressure on the sash stilenotwithstanding the distance of the stile from the frame.

Other minor objects of the invention will be hereinafter set forth.

I will explain the invention with reference to the accompanyingdrawings, which illustrate some practical embodiments thereof, to enableothers familiar with the art to adopt and use the same; and willsummarize in the claims, the novel features of construction, and novelcombinations of parts, for which protection is desired.

In said drawings:

Fig. 2 is a vertical section on the line 2-2, Fig. 1;

Fig. 3.is an enlarged horizontal section on the line 3-3, Fig. 1;

Fig. 4 is an enlarged horizontal section on the line 44, Fig. 2;

Fig. 5 is a transverse section on the line 5-5, Fig. 4;

Fig. 6 is an enlarged detail through a modified form of spring box,including the spring and adjusting screw anchored in the adjustableslide rail; and

Fig. 7 is a perspective view of a modification of the housing.

As shown in Fig. 1, my invention includes a window frame having uprightside jambs 1 and 2, header 3 and sill 4 mounted in a wall opening, andin said window frame are mounted the slidable window sashes 5 and 10.

Upper sash 5 includes a top rail 6, a bottom rail 7, and oppositelydisposed stiles 8 and 9. Bottom sash 10 includes a top rail 11, a bottomrail 12, and oppositely disposed stiles 13 and 14.

On the inner faces of the frame jambs 1 and 2 are a pair of parallelslide rails which engage the opposed faces of the stiles 89'and 1314 ofthe sashes 5 and 10. The slide rails at the opposite sides 1 and 2 ofthe window frame are generally similarly constructed, and each comprisesfa metallicplatglS, having the outwardly pressed ice 2 trough-shapedportion 16, said plate 15 having side flanges 17, the outer ends offlanges 17 being inturned as at 18, as clearly shown in Fig. 4. Thetrough-shaped portions 16 serve as guide ribs which engage grooves 19 inthe opposed faces of the stiles 89 and 1314 of the sashes 5 and 10.

On one side of the window frame, as shown in Fig. 1, the slide rails1518 are secured in fixed position relatively to the jamb 2 of thewindow frame by means of screws 20 or the like which extend through thetroughshaped portions 16and into the jamb 2 of the window frame; whileat the opposite side of the window frame the slide rails 1518 may bemoved inwardly or outwardly With respect to the sash stiles 9 and 14. Atthis latter side of the window the trough-shaped portions 16 of theslide rails 1518 are provided with pressed countersunk holes 21receiving the countersunk heads 22 of screws 23. Conical shaped collars24 engage the undersides of the countersunk holes 21 and are maintainedin position to hold the heads 22 of the screws 23 within the countersunkholes 21 by means of collars 25 which are crimped around the screws 23adjacent the heads 22 and which engage the inner ends of the collars 24.The trough-shaped portions 16 slidably engage the customary grooves inthe outer faces of the window sash stiles.

As shown in Figs. 4 and 5, screws 23 enter spring boxes, each of whichconsists of two parts, i.e., a tubular housing 26 which is pressed intothe jamb 1 of the window frame, and a spring 27 of the hour-glass typewhich is securely anchored at its base or inner end within the housing26 by compressing the housing around deadend coils 28 of spring 27, theouter end of each spring 27 engaging the inturned end 29 of housing 26which end is provided with an opening 30 for the passage of screw 23.

In Figs. 4 and 5, each spring 27 has disposed between its outermostcoil, which is of major diameter, and the next adjacent coil of majordiameter one or more coils 31 of restricted diameter forming a helixwhich receives and engages the threads of screw 23, so that when screws23 are rotated the slide rail 15 will be adjusted towards or from thewindow frame thus allowing the window sash to be moved inwardly oroutwardly of the window frame thereby permitting the sash to betightened or loosened as desired. Such arrangement moreover providesthat the window sash may be removed from the window frame withoutnecessitating removal of inside stops from the window frame.

Fig. 6 discloses a modification of the spring 27, in which the outer endof the spring is reduced in diameter as at 32 for several inturned coilsdisposed within the outer end of the major length of spring 27, so thatcoils 32 form a helix adapted to engage the threads of screw 23, forperforming the same function as the reduced diameter helix formed bycoils 31 shown in Figs. 4 and 5 and described above.

In some embodiments the spring 27 shown in Fig. 6 may be used without atubular housing 26, such as shown in Figs. 4, 5 and 6, which has an endannular flange 29. In such embodiments a modified form of housing may beused, as shown in Fig. 7, in which the housing 33 has its inner endconforming with that shown in Figs. 4, 5 and 6, and has a peripheralflange 34 adapted to seat on the outer face of the jamb 1 of the windowframe. The spring 27 such as shown in Fig. 6 may be somewhat shorterthan the spring 27 of Fig. 4, and similarly anchored in the housing butneed not contact a housing end wall such as 29 of Fig. 4. This modifiedhousing f (Fig. 7) permits adjustments to be made-with respect to theslide rail 1518, although the same may not permit sufficient travel toallow the sash to be readily removed from the window frame without firstremoving at least one inside stop from the window frame.

My device may be used with the Weatherstrip slide rails of a double-hungwindow to allow proper adjustment of the sash at all times. Whenassembled, the parts would be as shown in Figs. 3 and 4. To remove thewindow sash from the window frame it is only necessary to raise the sash10 a short distance or lower the sash a short distance and then exertside pressure toward the spring box mounted slide rails 15-43 of anamount sufficient to permit the opposite stile to clear the stationarymounted slide rail, then swing the sash out of the frame. To install thesash in the frame simply place the groove in the stile over the trough16 of the slide rail 1518 on the spring mounted side; then exertpressure outwardly toward the slide rail 15-18 until the sash hastravelled a sufficient distance to allow the stile on the opposite sideto clear the stationary mounted slide rail and swing the sash intoposition within the frame. Both of these operations take advantage ofthe ability of the springs 27 to flex enough to allow the sash to beinstalled or removed with a minimum of effort. Alternatively, the windowmay be removed by uncovering the heads 22 of screws 23 and threading thescrews inwardly until trough-shaped portions 16 disengage from thegrooves in the window sashes to permit the window sashes to be swungoutwardly or inwardly with respect to the window frame. After the windowhas been replaced in position the screws 23 may be rotated to move theslide rails 15-18 toward the stiles of the sashes until the properengagement of the slide rails with the sash stiles has been effected,this movement being effected because of the threading of the screws 23in the helix coils 31 or 32 of springs 27 which are anchored in housings26 or 33.

The sashes which are to be mounted in the window frame illustrated areoften of various widths and my present construction is so designed thatvariations within the limits of the adjusting feature may be compensatedfor. It also frequently happens that the window frame itself becomesdistorted or twisted and this distortion or twisting may also becompensated for within the limits of the adjusting feature.

After the sash has been installed it may swell due to moisture and itmay have some tendency to bind in the guide rails or slide rails. Thisis avoided by the present invention because the slide rails which areheld in position by the screws 23 may be moved inwardly toward the sashstiles against the compression of the springs 27 so that there is thusan automatic compensation for any swelling or spreading of the sashitself.

I do not limit my invention to the exact forms shown in the drawings,for obviously changes may be made therein within the scope of theclaims.
